Question

Explain how you can use the function rule 2x+3 to determine the output if yhe input is 7? Be sure to include the output in your explanation

Answer 1

To calculate the output for the function rule 2x+3 with an input of 7, you substitute 7 for x, multiply by 2, and then add 3, resulting in an output of 17.

To determine the output using the function rule 2x+3, you need to substitute the input value into the function.

In this case, the input is 7.

Here's the step-by-step explanation:

• Start with the function rule: y = 2x + 3.
• Replace 'x' with the input value, which is 7: y = 2(7) + 3.
• Multiply 2 by 7 to get 14: y = 14 + 3.
• Add 3 to 14 to find the output: y = 17.

Therefore, when the input is 7, the output of the function y = 2x + 3 is 17.
